[0002] After the ore is mined, it needs to be crushed. There are various types of ore crushers available, with small crushers being the most commonly used.
[0003] When a small crusher is in use, the crushed stone will splash out due to the rotation of the crushing roller, which poses a safety hazard. Some small crushers have tried to reduce the amount of crushed stone splashing out by increasing the depth of the feed hopper, which has some effect. However, in actual application, the increase in the depth of the feed hopper will increase the amount of pre-crushed stone above the crushing roller when feeding stone. The larger amount of stone will increase the downward pressure on the crushing roller, which can easily cause jamming and affect normal use.
[0004] Therefore, we propose a splash-proof safety crusher. Utility Model Content
[0005] One of the technical problems this utility model aims to solve is that some existing small crushers reduce stone ejection by increasing the depth of the feed hopper.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] Example 1: Please refer to Figures 1 to 6 The technical solution provided by this utility model is as follows: a splash-proof safety crusher, including a crusher body 1, a feed hopper 2 is provided at the top of the crusher body 1, and a discharge hopper 3 is provided at the bottom of the crusher body 1; a splash guard 8 is movably installed on the feed hopper 2, and symmetrically distributed operating plates 9 are provided on the top of the splash guard 8; it also includes a reset mechanism 10 and a positioning mechanism 11; the reset mechanism 10 is symmetrically arranged on both sides of the feed hopper 2, and the reset mechanism 10 is connected to the splash guard 8 for moving and resetting the splash guard 8; the positioning mechanism 11 is provided on the splash guard 8 for limiting and fixing the splash guard 8.
[0027] In this embodiment, as Figure 1 , Figure 3 and Figure 4The reset mechanism 10 shown includes support rods 1002 symmetrically distributed on the feed hopper 2, and reset springs 1003 ringed on the support rods 1002. Slide grooves 1001 are provided on both sides of the feed hopper 2. Sliders 1004 matching the slide grooves 1001 are provided on the splash guard 8. The sliders 1004 on both sides of the splash guard 8 are slidably sleeved on the support rods 1002. The reset springs 1003 are connected to the sliders 1004. In use, the power is turned on and the crusher body 1 is started. The operating plate 9 is pushed to move the splash guard 8. At the same time, the sliders 1004 squeeze the reset springs 1003. When the top of the feed hopper 2 is open, stones are put into it. After the stones are put in, the splash guard 8 is released. The splash guard 8 will be reset by the elastic force of the reset springs 1003, thus covering the feed hopper 2. This saves the step of manually pulling back the stones, facilitates quick sealing, prevents the stones from jumping out, and allows for stone crushing.
[0028] In this embodiment, as Figure 1 , Figure 5 and Figure 6 As shown, the positioning mechanism 11 includes a mounting sleeve 1101 disposed on the splash guard 8. The mounting sleeve 1101 has a sliding cavity inside, and a positioning block 1103 is disposed in the sliding cavity. The splash guard 8 has a through hole 1105 that matches the positioning block 1103. One side of the positioning block 1103 is an arc surface, and the other side is a straight surface.
[0029] A connecting rod 1102 is provided on the top of the positioning block 1103. The top end of the connecting rod 1102 extends to the outside of the mounting sleeve 1101. A thrust spring 1104 is sleeved around the outside of the connecting rod 1102. The thrust spring 1104 is connected to the positioning block 1103. The elastic force of the thrust spring 1104 will cause the positioning block 1103 to move downward. The top end of the connecting rod 1102 has an extension portion that can be used as a limiting component to prevent the positioning block 1103 from disengaging from the mounting sleeve 1101.
[0030] like Figure 5 and Figure 6 As shown, during use, when the anti-splash plate 8 is pushed, when the arc surface of the positioning block 1103 contacts the inner wall of the feed hopper 2, the pressure will cause the positioning block 1103 to compress the thrust spring 1104 and move upward. After the positioning block 1103 passes the side wall of the feed hopper 2, the reset force of the thrust spring 1104 will force the positioning block 1103 to reset. At this time, the straight surface of the positioning block 1103 contacts the outer wall of the feed hopper 2, which can prevent the anti-splash plate 8 from resetting and moving. Thus, the operator can use cleaning tools to clean the crushing roller and other parts inside the crusher body 1, which facilitates the maintenance of the crusher body 1, reduces maintenance costs, and facilitates use.
[0031] In this embodiment, as Figure 1 and Figure 2As shown, a discharge port 4 is provided on one side of the hopper 3. A matching guide hopper 7 is provided below the discharge port 4 on the hopper 3. An installation port 5 is provided on one side of the hopper 3. A filter screen 6 is provided inside the hopper 3. The filter screen 6 is inclined and its lower end is flush with the guide hopper 7. The bottom of the hopper 3 has an opening. During crushing, some unevenly crushed stone particles will be screened off by the filter screen 6 and directly discharged, while some stone particles that cannot be screened off will be discharged from the discharge port 4. Before use, the operator can place receiving devices below the two outlets to realize the function of rapid material separation, which facilitates the separation of large and small particles, so as to facilitate the subsequent use or processing of different types of crushed stone and improve its practicality.
[0032] Example 2: Please refer to Figures 7 to 8 The technical solution provided by this utility model is as follows:
[0033] Unlike Embodiment 1, this embodiment also includes a limiting component 12. The limiting component 12 includes a damping rotating shaft 1202 disposed on the hopper 3. A freely rotating limiting plate 1201 is disposed on the damping rotating shaft 1202. The limiting plate 1201 can be flush with the groove of the mounting port 5. The damping rotating shaft 1202 can keep the limiting plate 1201 stable without external force through friction, so that the limiting plate 1201 can be stably limited and avoid the displacement of the filter screen 6 caused by vibration during the use of the device.
